Operating systems

Chief Database records time series data in real time. Data is compressed to reduce disk requirements and improve performance. Redo logging and caching provide high performance on minimal hardware, with minimal data loss in the event of hardware failure. 1 million coordinates can be processed per second on server-level hardware. All interfaces are SOAP; allowing for easy integration with other systems and Web sites. Data is usually from a telemetered resource, but can also come from SNMP. Chief Trends allows for trending data inside Firefox. Chief Calculator is a Perl calculation engine to manipulate the data in whatever way you want.

Actual Storage calculates the actual storage capacity of secondary storage mediums, such as hard drives, CDs/DVDs, and USB drives. It can handle units from KB (1000 bytes in the decimal system) to YB (1000^8 bytes in the decimal system).

Dateutils are a bunch of tools that revolve around fiddling with dates and times in the command line, with a strong focus on use cases that arise when dealing with large amounts of financial data. Their target market is shell scripts that need date calculations or calendar conversions, and as such they are highly pipe-able and modeled after their well-known cousins (e.g. dtest vs. test, or dgrep vs. grep).

Corlpack is a faster Ada implementation of the basic types from the R Language. It includes calculations with units of measurement, a broad range of other basic types such as urn-like identifiers, coordinate, and monetary amounts. Basic types are represented as 128-bit UUIDs so heterogenous arrays, without predesigned structure, can be easily built. Heap allocation for complex structures is minimized, hopefully resulting in much shorter and more predictable execution time. An API with a small number of generic functions
aims to simplify Ada programming for computational applications, especially for scientists from non-IT fields.
